Deductions & credits

@victor29 - you were right. You can't e-file without addressing the error.

@MarilynG1 - FWIW, your statement, "Yes, it looks like the Carryover Amount for 2016 should not be -3,561, but rather 59,756" doesn't strike me as correct. Except for the last line of that table ("Carryover to [year]"), the Carryover column in the screenshot that @Sky Mile shared is not a running total, but rather just a calculation for each individual year (specifically, "Foreign Taxes" minus "Utilized"). Hence it makes sense that a value of -3,561 is reported in 2016 since 0 minus 3,561 = -3,561.

It's a shame that the approaches to fix this issue that were suggested by TT support to @victor29  and @Sky Mile are slightly different. With the former approach, you are only making an adjustment for the amount in excess of amount utilized (i.e., 26, in my case), whereas with the latter approach you are making an adjustment for the total amount utilized (i.e., 91, in my case). Obviously, the latter approach is more advantageous for the tax payer. Since both approaches involve reallocating money between years, I figure may as well go with the approach that is more advantageous. If anyone knows anything to suggest this is not "legal", please advise.

@antx2022 - I don't quite understand what you mean by, "Shall i report it in 2021 as well ?," but if I am understanding your situation correctly, based on the procedure that @Sky Mile shared, you would adjust things as follows on your 2021 return. All numbers are examples. Hope that helps!
