Retirement tax questions

I tried that but it did not work for me.  First after I put in the amount from the 1099R, I could not put 0 in line 4b (taxable amount) without an override and second I found NO way to put the annotation QCD on line 4b as directed by IRS instructions.   However as soon as I changed my age, those lines were filled in properly by Turbotax through the interview process.

Then after I had it entered correctly, I went back and changed my age back.  When I fixed my age to the proper age, the forms remained the same (correct).  So I am not lying about my age to the IRS.  Only briefly to Turbotax to work around their bug.
