I did my taxes last Sunday. I used TurboTax. This year I didn't need to call tech support and talk with them for an hour. For some reason last year the files for the Mac version were locked which prevented the program from working correctly. I had to download a program that would unlock the files. Then I had to download the updates to the program. Finally, I was able to get the program to work.
This year no such problems. So I did everything on Sunday. I was even able to download DC tax forms and file my DC return too. As I said that was Sunday. Friday in the mail I received my DC tax return.
It is so great when things work exactly as they are supposed to.
