Also, the reason I'm amending the return is that I accidentally put into Turbotax that the SEP/SIMPLE checkbox was checked. When, in fact, that box on the form was not checked by the sender. By my stating that this box WAS checked my return showed I owed money. When I changed the check box to be blank (as it should have been), the IRS owes me money. So the 1099-R itself actually did not change. I simply changed my input into the 1040 form to accurately reflect what was actually on the 1099-R. I'm concerned that this will make it impossible for the IRS to know what to look for
