How does the IRS know if I received a one time Estate Executor fee?

They don't unless you are issued a tax reporting statement (e.g, a 1099) or you report it voluntarily in the absence of a tax reporting statement.

The IRS may or may not be informed by the estate directly, but you should still report your income accurately.

Here is a tool from the IRS to help determine ‌taxability: Are the fees I receive as an executor or administrator of an estate taxable? As well, reimbursements you received for your expenses of being an executor aren't income.

The IRS may or may not be informed by the estate directly

The way the IRS is informed is via a 1099 unless the payment is below the threshold. It is highly unlikely that the IRS would be able to match the fiduciary listed on the 1041 to a fiduciary fee reported on the same form. Regardless, the fee should be reported no matter the amount.
