Signing Bonus Repayment (941-X)

Hello guys,

 

I left my job about a month ago and, as part of my resignation letter, I handed them a check corresponding to the NET signing/relocation bonus since the repayment is happening on the same tax year as the distribution.

 

My question is, it has been a month since I handed them the check and they have not cashed it so I was kind of wondering if there is a requirement for them to wait until the end of the quarter to file a 941-X and then cash the check. I have sent HR and payroll multiple emails and they have not responded. The money is and will remain on my account until they cash it but I am just curious to see if someone has experienced a similar situation.
