When is my Health Care FSA Carryover balance available for me to use?

The Carryover amount is available to pay 2021 expenses during the 2021 plan year run-out period (through March 31st, 2022) and 2022 expenses after your 2022 election amount has been exhausted. Expenses incurred during the 2022 plan year will pay first from your 2022 account balance, and any Carryover from 2021 will pay second.
