Unable to Efile due to Form 8888

Hello - I am trying to amend 2022 taxes via turbotax (a small 1099 unexpectedly came in).  I went thru the steps of Amending the Return and saw the additional amounts due. 

 

I try to e-file, however, I receive (a) error messages on Form 8888 to note how much in Ibonds to purchase (which doesn't make sense since I owe money).  After entering "0", and trying to transmit, I get (b) error messages that these fields must be blank.  Change it again, goes back to (a).  Never ending loop that won't allow me to transmit.  Is there a way to bypass this? Did I enter something incorrectly?  This is very odd.

 

Thank you!
