I also see numerous errors on TY2021 Form 2210. The errors are in Part III Section A lines 10-19.
On Line 10, it is not transferring the correct values from Schedule AI line 27.
On Line 11, it is not transferring the correct values for estimated tax paid and tax withheld.
Once those two are wrong, that leads to Lines 17 and 18 (underpayment, overpayment) being incorrect.
Once those are wrong, Line 19 (Penalty) becomes incorrect.
In my case, I should not be paying a penalty, but TurboTax is showing a penalty.
I am using Turbotax Home and Business Desktop for MacOS
