"and mark entire amount rolled over?"

Was there withholding on that distribution and this was a net check? If it was not made payable to the new plan/account, but to the taxpayer, you'll want to confirm they really put the entire amount in (had to make up the difference) the new plan/account.

You stated plan, not account. For example:

"Any taxable eligible rollover distribution paid to you from an employer-sponsored retirement plan is subject to a mandatory income tax withholding of 20%, even if you intend to roll it over later."
