Schedule 2, Line 8 calculates "Additional tax on IRAs or other tax-favored accounts" that I believe is in error

I rolled over money from a Profit Sharing Plan to a traditional IRA, so I received a 1099-R. I believe the entire rollover is tax-free. However, 2022 turbotax Premier (download) calculates an "Additional tax on IRAs or other tax-favored accounts" that is entered on Line 8 of Schedule 2, which then shows up on Line 23 of Form 1040(2022). I have looked closely at my entries on Form 1099-R, and believe they are correct. I have not made any excess contributions to any other IRA, and I am too young to need to take Required Minimum Distributions. How do I get Line 8 of Schedule 2 to be zero? Thanks.
