I don't have Form 6251 in my 2022 return but Turbotax is asking for the entry on line 4?

Turbotax is asking for the entry from my 2022 FORM 6251, line 4, that I used for AMT.

 

I don't have Form 6251 in my 2022 return

 

I clicked on the link: "What if I don't have Form 6251?" and get the following paragraph.

"If you think your AMTI might be different than your "regular" taxable income (Form 1040, line 10), you'll need to determine what your 2022 Alternative Minimum Taxable Income was and enter it here. If you don't know your AMTI, most people will get the same result using your "regular" taxable income (2022 Form 1040, 10)."


However line 10 on my 2022 Form 1040 is blank; there is no entry.

 

I hope this all makes sense to someone. What the heck do I do?

 

Thank you
