Form 8889-S Health Savings Accounts

Both spouses have HSA with high deductible and both employers contributed signified by Code W on their Form W2.

Form 8889-S Line 13 calculates the HSA deduction as the smaller of Line 2 (HSA contributions you made in 2020) or Line 12 (calculated available deduction based on plan type and code W from Form W2).

Line 2 is $0 because on Code W amount (which doesn't belong on Line 2)

Line 12 is $3,800 (Family plan $7,100 less both spouses code W amts of $3,300)

Line 13 should be $0 but it's appearing as $3,800.

Line 13 is being carried to Page 1 as a deduction as it should but the amount should be $0 not $3,800.

Am I doing something wrong or is this a software glitch?
