Started 1099 Employment May- How to catch up on 1/4 payments

I was unemployed this year until April 29, 2024 when I was hired as a 1099 employee. I'm paid bi-weekly and anticipate earing $91,540 throughout the remainder of this year. My first paycheck was 5/10/24 and I had only received 3 paychecks by the June estimated tax filing date. I obviously didn't file anything in April as I was unemployed, and did not file anything in June as I had just started working. What do you suggest I do at this point? Should I send in a payment for June now even though it is late? If so, should it be for half of my annual estimated taxes? Or should I send 3/4 of my annual estimated taxes with the September filing?  Just not really the best way to catch up at this point.

Thank you.
