Agreed! I just tried manually changing the date from 12/31/2020 to 12/30/2020 in Form 1116, and tried to re-submit my tax return, and it got rejected once again. The problem still persists after I installed the recent updates (March 11 updates).
My situation is exactly like gg1961 said: "This problem happens if you are submitting a "correct" 1116 form, need to have an AMT form, and are using the simplified method for AMT calculation."
TurboTax, please find a fix soon! I am waiting for your team to come up with a hot fix soon!!!!
