Thanks DanaB27 for the detail reply.
Couple more questions:
1. I will file amendment for 2021 to include solar installation credit and I understand that I can only mail-in (e-file period ended for yr-2021).
I will have new TurboTax (Amend) computer-file, along with original turbotax file(computer-file) in 2021 that I filed originally.
When I start a new 2022 filing, I should choose the new Amend-2021 computer-file to continue [Transfer Return], correct? not the original one without solar credit...right?
2. If 2021-Amend shows carry-over (i.e. 5695 line 16), still enter that in 2022 filing? e-filing may see conflict (since 5695 does not exist in their system yet, likely)?
Even I have mailed in 2021-Amend soon enough, IRS would possibly not process my amendment in time when my 2022 filing be processed (I will do e-file).
In regards of what to enter in 2021-carry-over for my 2022 filing, whatever my 2021-Amend turned out (i.e. 5695 line 16) in my 2021-Amend that shown by TurboTax, I shall put that into my 2022 filing, correct? Even they have not yet processed my 2021-Amend, likely, by the time the 2022-efile got processed.
Not sure if this can be a conflict and becomes "flagged" (e.g. trigger auditing).
Thanks very much
