How can i avoid the self employed fee if this year i only did 1 small job?

Did you get a 1099Misc for it?  If you got a 1099Misc or just cash and did not get a W2 that is self employment income.  You can enter 1099Misc or cash self employment income into Online Deluxe and Premier but if you have any expenses you need to upgrade to the Self Employed Version.

Or use Turbo Tax Free File website. It 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 $36,000 or less
Active duty military with AGI of $69,000 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.
