Can I get service code

For what?  For the current online version or the Desktop Activation code?

If you want to file for free you can try the Free File website which opens in mid-January.

Turbo Tax Free File website is free for federal and state. And has more forms than the Federal Free Edition, like the full 1040 return and Schedules A, B, C , D, E, F, EIC, H, K-1, SE, etc.

To qualify for the Tax Freedom website you just need to meet one of these 3 things
AGI $39,000 or less
Active duty military with AGI of $72,000 or less
OR qualify for EIC (earned income credit.)

In order to use the Turbo Tax Free File, you have to start it at a special website. If you use the Sign In button on the top right I hear it brings over your work.
