Which version of TurboTax are you using (online or desktop/installed)?
Regardless, you should be able to go back through the interview and change the answers to the relevant questions.
Which type of entity issued the K-1?
If it is an S corporation, 199A income is reported on Line 17. If it is a partnership/multi-member LLC, 199A income is reported on Line 20.
If you have either of those two entries the program will default to the QBI deduction.
I just have one rental property and didn't realize I needed 250 hours of work with the rental to qualify. Now I want to remove it from my CD installed form. How can I do this?
Remember the 250 hours is a safe harbor given by the IRS and not the law. The IRS says that if you are over the 250 you are safe but if you are under you may still qualify to take the deduction.
