Deductions & credits

Forgot to add more details. So both me and my wife has HSA accounts. My health insurance covers my family. Her health insurance covers herself. In 2018, I contributed $3550 to my HSA and she contributed $3350 to her HSA. Thus, the total is $6900, which is the max limit. I thought we are good. But it seems TurboTax thinks I contributed $100 more to my account. Apparently, it is using the individual limit to measure my contribution, which is $3450. Is it a bug?
