When assessment is pending before ITAT and if opted for VSV scheme, whether interest raised under 220 is also exempted?

I have submitted FORM 1 and 2 under Vivad se Vishwas Scheme for which i have received Form 3 on 23/12/2020.

I want to know the time till which i have to file Form 4

Moreover, Govt has released notification on 27/10/2020 increasing the time limit to make payment till 31/03/2021

So altogether read with notification please suggest me the time till when i can file Form 4

If an assessee has been imposed interest on refund that under section 234D, can he get this amount waived if he adopts dtvsv scheme?

APPEAL CAN BE WITHDRAWN ONLY UPON ISSUANCE OF CERTIFICATE IN FORM 3 BY DESIGNATED AUTHORITY. IN THE MEANTIME IF OUR APPEAL FIXES BEFORE ITAT, CAN IT BE DISPOSED OFF OR WILL IT BE TREATED AS DEEMED WITHDRAWL?

I had gone on an appeal to ITAT against the order CIT(A) which was passed in Aug 2018. ITAT passed an order in the month of Nov 2020. Can I apply under Vivad se Vishwas scheme

By mistake I have paid self tds 2014-15 in favour of banks TAN in place of my PAN number. Can I fill vivad se vishwas form to correct same. I have already rejected demand generated by cpc and sent applications to A.O. For corrections, but from 4years it’s pending and new demand raised by cpc.
Please suggest how to solve the issue?

Referring to Question 49 of FAQ dated 22 April 2020, where Question is “Once declaration is filed under Vivad se Vishwas, and for financial difficulties, payment is not made accordingly, will the declaration be null and void?” Answer given is “Yes it would be void.”
In continuation to the question, sub-section 2 of Section 4 states that “Upon the filing the declaration, any appeal pending before the Income-tax Appellate Tribunal or Commissioner (Appeals), in respect of the disputed income or disputed interest or disputed penalty or disputed fee and tax arrear shall be deemed to have been withdrawn from the date on which certificate under sub-section (1) of section 5 is issued by the designated authority.”
My Query is ‘Will our appeal be reinstated if we cannot make payment due to financial difficulties or can we make fresh appeal?’

We have filed an Appeal before the CIT (A) with 4 Grounds of appeal. We want to make an application for only One ground of appeal under the Scheme. Can we do so ?

DEMAND UNDER SECTION 154 CAN APPLY FOR VIVAD SE VISHWAS

If the assessee received an order wherein there were 4 additions made to the Total income. The Appeal filed in CIT is also against all 4 additions made in the order. Can the assessee avail the benefits of the Vivad se vishwas scheme for any one or two (i.e, part) of the total additions made by the order?
Kindly guide.
