All distribution must be reported.  What do you mean "cancelled"?  Where is the money?
What code is in box 7?

The money is with the broker re-deposited back into the account. Yes box is checked!
We did not cash the check and let it expire.

Then you must enter it and say you moved the money to another (or the same) retirement account - rollover.

If you fail to enter it as a rollover, the IRS will assume yiu took the cash and send you a bill for the tax on the entire amount.

Enter a 1099-R here:

Federal Taxes,
Wages & Income
I’ll choose what I work on (if that screen comes up),
Retirement Plans & Social Security,
IRA, 401(k), Pension Plan Withdrawals (1099-R).

OR  Use the "Tools" menu (if online version under My Account) and then "Search Topics" for "1099-R" which will take you to the same place.

Be sure to choose which spouse the 1099-R is for if this is a joint tax return.
Be sure to pick the correct 1099-R type: Standard 1099-R, CSA-1099-R, CSF-1099-R, RRB-1099-R.

[NOTE: When you get to the "Your 1099-R Entries" screen where you can add another 1099-R, use "continue" to keep going as there are additional interview questions after that screen in most cases. You can always return as shown above.]
