Cover letter for application?

Just curious. . wondering if I’m being too ‘professional’ and not thinking like an academic.

Anyone know if a cover letter is appropriate for an application to a post-bacc program? Was thinking of throwing something simple on along the lines of ‘enclosed is my app, transcripts, etc, look forward to hearing from you’

I overthink everything . . .

I wouldn’t bother. Just make sure the application is done well.
