I just filed via Turbo Tax

[question everything]

5. I had an interesting experience that flummoxed even a representative

I donated shares of stock (Apple) and had to enter the cost basis.

TurboTax would not accept it, "invalid" kept saying.

Finally the representative suggested to round the number of the cost basis - was really low - and it worked.

And then I figured that most shares prices extend to three digits after the period and TurbuTax, working with dollars and cents would accept no more than two digits. And that was the issue.

I hope to finalize it later this week.
