The system is saying that I have 350 in contributions to my HSA. I contacted them and I do not have anything that I can withdrawl. Should I ignore that message?

I switched employers in Sept. of last year. The system informed me that I had $350 in excess that needed to be withdrawn or I would receive a tax penalty. However, when I called the HSA to inquire about the excess money I was informed that I do not have funds that can be withdrawn.
