I got two stimulus checks in 2019. Now it appears turbo tax is including it as taxable income. I thought it wasn't taxable income? How do I reverse that?

The payments were added up by Turbo Tax, and my federal tax due increased a lot.  That doesn't seem correct to me.  My understanding was that the stimulus payments received in 2019 was not taxable income.  How do I make it not taxable on Turbo Tax?
