My issue is still not resolved but with new findings: I can see the data are already imported into TT, so not a data import issue, but TT won't show two 1099-DIV in the returns. Another call to support and they had no clue what happened. In the end TT support suggested I manually enter the forms but they did not know how to do it. I figured out myself and it worked at least. My experiences with 4 support stuff: None of them can fix anything, and three of them did not even care. Do not understand why TT is rated as best tax prep app?
