Yes, found out after posting the question.  Thank you very much for the reply  

Why it has to be entered after year of sale will not be answered by the IRS.  Thought if reentering the info would have an effect   But, no, just for info purposes I guess.

The original installment happened in 1999.  No problem since I bought a Fujitsu scanner from Intuit about 7-8 years ago ($800+) and scanned all the paper files (18 years worth) on external flash drives and sold the file cabinets.  Can provide clients prior years returns for a price.

Best investment was the scanner back then.
