Retirement tax questions

OK dmertz--I think I got it . . . finally!!!!  

 

I read more guidance, both TT and Pub 721.  The bottom line is:  use Box 2a, when answering this question; not the gross distribution amount in box 1. 

 

As you stated, since the entire amount is taxable, this eliminates the need to calculate anything.

 

Thanks again.
