That info is all correct and if you follow the form 2441 you will see how the FSA usage is deducted first and then if you have any expense after that you would get a credit. Be aware that the 2021 tax year was very different and now the rules are back to the norm.
For instance if you had 2 kids in day care and spent $6000(or more) then the $5000 of FSA reduces the max allowed of $6000 leaving $1000 for the credit.
