I accidentally put the form 1095-C for $110 on the HSA I tried to fix it but it won't let me delete it.

Delete the entire form and do it over.

Open your return in TurboTax. (To do this, sign in to TurboTax, and select the Take me to my return button.)

In the left side bar, select Tax Tools> Tools.

In the pop-up window Tool Center, choose Delete a form.

Select Delete next to the form/schedule/worksheet and follow the onscreen instructions.
