Go back through the section of your return where the 1099s were entered to be sure that the format for the EIN/TIN entry was entered in the same format as the number reported on your form in hand. There is a toggle to allow either the xx-xxxxxxx or xxx-xx-xxxx format.
Additionally, while you are double-checking things, it wouldn't hurt to go through any other tax documents you may have entered (W-2, 1099-R, etc.) to verify that the EIN on those is correct.
