Retirement tax questions

I don't think anyone would recommend that.   In addition to the distribution amount and withholding, there are other boxes on the 1099-R that have to be entered correctly.

What tax year return are you preparing?  A 2015 return?  Online TurboTax for 2015 will shutdown after November 15, and unfinished returns will need to be moved to the desktop version (CD/download).  Are you using Online TurboTax or the desktop (CD/download) version?

Are you referring to 2015 1099R's that you lost or didn't receive, and have to get duplicates?
