Last year the online version did not accept the W2-G and I had to purchase a download. Did you fix this problem or do I have to download again?

You would need the Deluxe version (or higher) in TurboTax Online for a W2-G.  Since you purchased a download last year, you may want to do so again, as it will be easy to transfer your 2017 info into 2018.

You may qualify for the Free File Program, which can also handle a W2-G.
