I just learned that I need to file a 1099 Misc form for my side job. I have already filed my state and federal taxes, do I need to amend them in order to file the 1099?

Yes, you will need to Amend your return in order to include the income reported to you on the 1099-MISC for your side job.  This income, and any related expenses, should be reported on Schedule C.

You will need to Amend your Tax Return using Form 1040-X once the IRS has fully processed your original Tax Return and you have received your Refund. You can click here for instructions on Amending your tax return: How to Change a Tax Return You Already Filed.  

The 2018 Form 1040-X is not available yet, but should be within the next week.

Note: You SHOULD NOT make any changes on your return in TurboTax until this form becomes available.
