Deductions & credits

I have a question about 8915-E from 2020.  When I was going through 8915-E to answer questions for 8915-F, I noticed a possible error.  On 8915-E, line 4, it states to complete column (c) if line 4, column (b), is more than $100,000.  Otherwise, leave column (c) blank....  My line 4, column (b) is less than $100,000.  But it appears TurboTax placed 100,000 in column (c).  It also appears to be in a different font.  Did anyone else notice this when preparing taxes this year?
