For HSA, MSA contributions, I cannot delete what is showing. The edit button does not allow me to clear the contribution. How do I clear the contribution?

Check your W-2 to see if there was an amount reported in box 12 with code W.  That would indicate a contribution to your HSA through payroll deductions or employer contributions.  

If there should not have been any contributions, you should discuss this with your employer if an amount was reported on your W-2.
