Why does automatic Tax documents (1099) import from Betterment and Etrade doesn't work for me but works for my colleagues?

ask them to tell you what you are doing wrong.
If you have too many transactions, Online Turbotax won't handle it.

I don't think Im doing anything wrong, every year TurboTax automatic import tax document doesn't work... How can i get an answer from TurboTax support?

how many transactions ? If you have too many transactions, Online Turbotax won't handle it.

if you are an active investor you should be aware that Box A and Box D transactions with no adjustments do not have to be itemized on Form 8949. Thus there is no reason to import those transactions.

instead report subtotals on schedule d Line 1a  for A and Line 8a for D

If you have wash sales, it gets more complicated since those have to be itemized on Form 8949 and the summary totals adjusted accordingly.
