Thanks for your reply! I'm okay with just starting this year - it was my fault and my loss, but I would like to start recouping it.
My concern is with the mechanics of "just add the basis to this year's" return. I last claimed a basis on Form 8606 in 1997. Since 2017 I've submitted four Forms 8606, only to provide Part II, Conversions, information with equal Amount Converted and Taxable amounts, mentioning nothing of a basis. I should have shown (and used) my basis on Line 2 each of those years.
I guess my question boils down to... By submitting several Forms 8606 in recent years with nothing on Line 2 (basis), can I now just start using the basis last reported 27 years ago? It just seems that might raise a red flag.
Thank you.
