Box 12 of W2 not reporting HSA contributions
My employer did not code my HSA contributions correctly in Box 12 but they are deducted from Box 1, 3, and 5. I've tried updating the amount of employer contributions through a cafeteria plan on TurboTax but it will not let me edit that box. I'm only able to adjust the after-tax contributions. How can I get this reported properly as my employer will not issue a corrected W2?
