Married filed jointly - Seperate HSA Plan shows twice as much excessive contribution

My wife and I filed together。

She contributed $7300 for our family HDHP HSA plan,

I have a seperate coverage and I contributed $600 through my own payroll.

Now Turbo Tax notified us that "I" had an excessive contribution of $1200 and we need to withdraw $1200 to avoid extra tax.

 

Anyone know what's the issue here? Where does the $1200 come from?
