Retirement tax questions

I agree that the boxes exist to I see a “7” and a”D”.  However when completing the final review you will an error asking you to choose whether this account is an “IRA” or an 503B or “other “.  The files may exist but the review is where the problem is.  I did get online help and the turbo tax rep said a paper copy was the only way to submit a 1099r with a 7D.  Is that true?
