This was taken from the FAQ section of CDC.gov .... they indicate they will accept both types of tests. We've gotten a list of several clinics that can supply them from the Airbnb owner we are staying with. We are going to head on down and hope they get it ironed out by mid February. We'll keep monitoring - I'd guess things can change quickly!

When do I need to get a test to travel to the US? And what kind of test do I need?

Get tested no more than 3 days before your flight to the US departs. Make sure to be tested with a viral test (NAAT or antigen test) to determine if you are currently infected with COVID-19. Also make sure that you receive your results before your flight departs and have documentation of your results to show the airline.
