Help overriding TurboTax error in AMT credit carryforward and carryover credit

There is another thread where a user discovered an issue with the AMT carry forward and many other users replying that the IRS has audited and also identified an issue with this part of their return.  

I discovered the same thing this year because turbotax had entered a significant credit amount for "credit for prior minimum tax".  Upon tracing it back through all my returns, it is a turbotax error from over a decade ago.  

Fortunately, none of my returns reflected the credit before, so it shouldn't be an issue of underpayment of taxes for any returns I've filed.  Unfortunately, on the other hand, because it hasn't reflected a credit, I also did not notice the turbotax error when it first happened.

My question is how can I fix this in my 2021 taxes.  I've reviewed my return using the forms viewer and it doesn't seem I can override schedule 3 line 6b (or any of the preceding forms like 8801) so that there is no carryover credit reflected on my 1040.  

Thanks for your help!
