Deductions & credits

I checked again today - TurboTax is still DELETING or ZEROing out my Form 2210 data and showing a "zero" for my AGI.  And re-assessing the penalty. 

 

I re-entered my data. Again. Penalty went away (briefly while I'm finishing up the form). Exit the form Q&A, and penalty comes right back! All the form data is gone. Again. Re-assesses the penalty. 

 

Any suggestions for getting around this bug? At this point I'm not seeing a workaround short of jumping to another competitors platform...

 

Thanks,
