Incorrect HSA contribution limit in TT 2020

I need to estimate my 2020 taxable income before the end of the year, so I just bought TurboTax 2020 and started entering the info I have so far.  I am over 55 years old, and I contributed $4550 to my HSA, which all sources say is correct. But TurboTax 2020 is saying I'm $50 over the contribution limit.
