After you file

No, no one in Community can even look at your tax return, and definitely not change it, even with your permission. 

What Community can do is give you answers to your tax questions, step-by-step directions, and advice about tax matters. 

If the issue is a duplicated 1099-R, this is how to remove the duplicate:

1. Open your return.
2. Select Federal, then Wages & Income.
3. Scroll down to IRA, 401(k), Pension Plan Withdrawals (1099-R), under Retirement Plans and Social Security, select Start or Revisit to the right.
4. You will see a screen similar to the image below. Select the trash can icon to the right of the duplicate entry to get rid of it.
