Ammended 2018 return and now I need to ammend again

Selecting Ammed return for an ammended return doesn't work.  I have tried deleting the form 1040X from the ammended return, saving it, and then selecting ammend on it, but that doesnt reflect the additional refund I got from the first ammendment, nor does it bring the refund balance back to zero.

 

Any tips/help is appreciated.


Thanks,


Eric
