Retirement tax questions

Thanks, @fanfare, that was my original plan.  It seems the basis will not change since my father died since no credit has been claimed against the basis yet.  The basis only changes when making new contributions or when making distributions and using part of the basis to lower the tax.  Since I have done neither, it seems the basis should be unchanged and I should be able to use it going forward.

 

I'd like to hear about the workaround for the 8606 name:issue.  Thanks.
