2019 Taxes - Wife's 1099-MISC requiring schedule C information
Fair warning - I have no idea what I'm doing with taxes, it's why I'm using TurboTax.
I am behind on filing taxes. The first one I have to file is our 2019 taxes. Due to this being a past tax year I have to use the downloaded version of TurboTax.
Our main income is my full time job. This year my wife earned $700 doing work for a local theater. She got a 1099-MISC. I have entered the information, and am at the "Smart Check" section, and it tells me the software found errors on my federal tax return. They are questions about a schedule C. I have no idea what this is, how to fill it out. It's asking a question about whether it's qualified business income, the principal business code, etc?
How do I find the answers to these questions? When my wife did the 2019 work, the theater she did the work for got her to login to intuit and fill out a tax form before working. I can't get that form anymore, because when I login to intuit using the credentials she used, Intuit wants me to sign up for a self employed account, which we don't need. I just want to find out what form she signed.
Am I meant to fill out a schedule C for my wife? How do I figure out how to fill it out?
