I put the wrong answer in HSA distributions. I did not take a distribution but Turbo Tax will not let me edit or change that answer or remove that amount. HELP!

I say I withdrew the entire amount as a distribution.  I did not understand the question and answered it wrong.  I used it all for medical expenses.  How do I change the answer or edit it or remove that amount?  I do not want to have to start over on this return.  How do I fix my mistake and error.  None of my HSA is taxable but I answered wrong and it is being counted as income.  HELP?
