"This is what the memo from her employer states"

There is a New provision that the employer has to State this separately in a statement or show it in an Info box on the W2, exactly because of Form 7202.

Form 7202 is for self-employed persons, such as your client might also have a sidegig of that type. These people are allowed to have parity in that FFCRA but must take into consideration any amounts already included in their "real job" for FFCRA. Because they don't get to maximize the rule for Both provisions (as employee and as SE).

You won't do anything with that info unless your Employed client also has their own SE operation.
