Will this affect my return amount?

[Mfmash1]

Hello,

So while filing my tax return, the first question was if I did still work at my job, and I wrongly answered yes. Would that affect the tax amount? Or TurboTax rely on the numbers on the W-2 form and calculate the right returns?

The correct tax liability will be calculated based on the amounts reported on your W-2.

Thank you so much.

Also, Turbotax compared my 2020 tax with 2019 and it appeared that my 2020 is less than 2019, so suddenly my tax return jumped a couple of hundreds dollars just because of that. Is that normal? does the IRS double check my information?
