I got a call last week that payroll over paid me

Like 630.00. From 2 months ago or something. That's a bunch of crap.. Ugh if I pay before 3018 ends I will pay less than that amount.. If I pay 2019 I pay more.... And there is only 2 pay checks left this year for me. Not a good time Christmas season is not the right time.. Well no time is but definitely not now ugh
