I was at Walgreens today for Omicron/Covid booster and asked about Covid testing for travel. They said Medicare no longer covers testing for travel. I think they said it would cost $129. Looked online and found that Walmart is testing for $75 - I’ll check tomorrow and may make an appointment there. I know there are some online proctored tests that were advertised at $19.95 but you have to download their app and jump thru hoops to get signed up.
