Thanks for the reply, that is exactly what I tried a few days ago and it worked.
While I could be wrong, I am sure I did not check any box suggesting I purchased anything before 1971. I believe the 1099s that caused the problem were automatically imported and automatically checked that box. In the "review" process later I did find that box and unchecked it, but it would still not get past the error until I found the D-71 forms and deleted them. Would be good if Turbo Tax could detect that once the box is unchecked it can ignore/delete an unused form rather than getting stuck on it.
