trans | first us passport help

i swear i've read something similar to this but can't find anything in tags or memories.

i'm applying for an expedited passport (never had one) so i can travel for business either late may/early june.

my DL says M but birth certificate and SSN still say F. i've had top surgery - i plan on calling the surgeon and getting the usual 'irreversible sex reassignment' letter, i'm assuming it needs to be notarized (i'll error on the side of caution and pay the extra money).

i'm anticipating flags going off for the differences in gender markers. i can't find anything on the us department of state site relating to any specific requirements for getting my application processed 'properly' despite the differences in gender markers.

any recent experience, links, advice?

thanks
