I think TurboTax has problem overwriting downloaded 1099 data. I know some of my data just disappeared for no reason. I ended up having to load data manually because the important function seems to overwrite or delete existing data. Glad I caught the error before filing.
Anyone else experiencing strange performance like this. Seems like if there are too many 1099 Div entries it may just over right one. I finally got things to work by manually entering my 1099-INT and 1099-DIV. It was very frustrating.
