Need Help With TurboTax 2020 Amended Return Glitch

I need to amend my 2020 tax return.  When I go into TurboTax 2020, I select the return I wanted to amend.  Once I get to the screen where I can actually start making changes, it immediately says I owe $374. 

The screen should say $0 for federal and $0 for state.  That is the expected behavior.

 

Upon further investigation, the problem is caused by a 1099-R, that was  part of the original submitted return.  Again, I made absolutely no changes in the amended return and it immediately says I owe tax.

 

  1. Is being double taxed for a 1099-R, when doing an amended return, normal behavior?
  2. If not, are there any work-arounds for this?
