I accidentally selected yes to the question “were you affected by a natural disaster” and I can not go back to the question to change my answer

If this is related to your retirement income, you would want to revisit the Retirement section to edit.  

If you have not filed, to revisit, here are the steps:

In TurboTax online,

• Sign in to your TurboTax account and select Pick up where you left off
• At the right upper corner, in the search box, type in "1099r" and Enter
• Select Jump to 1099r
• Follow prompts

Or  if this is related to any property damaged, follow here to edit:

• Sign in to your TurboTax account and select Pick up where you left off
• At the right upper corner, in the search box, type in "natural disaster" and Enter
• Select Jump to natural disaster
