I also had trouble finding it, doesn't seem like the online (browser) version has a "walk me though everything".
I was able to change my answer to the question by
- Click on federal (left menu)
- Click "Retirement Plans and Social Security"
- show more
- IRA, 401(k), Pension Plan Withdrawals (1099-R)
Follow those questions and it should take you back to the disaster relief question if you wish to change your answer.
