All of that has been resolved with previous postings. I am now filing my 2018 forms (after extension in April). I'm told that Turbo Tax does not support form 8606 for a deceased spouse with "basis". I was told to fill out a paper copy, out of Turbo Tax, of the 8606 for my spouse. I was directed on how to then enter the "basis" into Turbo Tax, and get it combined with mine, which I have done. The only remaining question is, how do I enter the taxable amount of RMD (line 15c) into Turbo Tax. Otherwise I will have to pay tax on the total RMD. Thanks for your help.
