How can I delete the HSA info since it never became effective as I was already on Medicare?

Please follow these steps to delete the HSA information:

 

1. Click on "Search" on the top right and type “hsa” 
2. Click on “Jump to hsa”
3. Continue and delete all information.

 

Please be aware if you had an HSA amount listed on your W-2 box 12 then you won't be able to delete this.

 

Please see How do I view and delete forms in TurboTax Online? for additional information.
