Q. Can you upload a 1098-E instead of a 1098-T?
A. No. They are two different documents with different purposes.
Q. What is the difference?
A. The 1098-E is to report the interest on a student loan. The 1098-T reports tuition paid and scholarships received.
I don't recall TT giving you the option of uploading. I think both documents have to be entered manually.
