Calculating the non-taxable portion of an RMD

I have a basis in my IRA. In previous years TT has asked me questions to assure that the basis is used to reduce the taxable amount of my RMD. This year I can't get TT to ask me these questions, so my entire RMD is entered as taxable.

 

1. Is there a way to get TT to interview me on this topic?

 

2. If not, what do I need to do to get the 8606 filled out correctly
