After you file

This is EXACTLY what I'm going through this year 2022- He filed in Feb received letter in March the payment posted in April but didn't apply until the end of May and only the amount for the state arrears was applied and Im still waiting on my portion of arrears as the custodial parent and they can't give me a time frame and he filed Single not jointly..it's So frustrating we're in June now Do you remember how long it took for your payment in 2019 ??? Any info would be helpful at this point because google isn't specific to my situation and the case Managers at the child support office are less informed then me at this point-HELP! Timeframe on  Offset arrears payment for the custodial parent- ANYONE???
