1099-r box 7 code g

I converted a traditional IRA to Roth IRA last year. I received a 1099-r showing the amounts as fully taxable in boxes 1 and 2a. Box 7 shows code G with a Y in the box IRA/SEP/SIMPLE. Turbotax is telling me this is wrong and it should not be B. I contacted the company that said is is correct. When I keep going through it does not appear to be a taxable event in Turbotax.

How should I enter this?

 

Thanks in advance
