My turbotax credit card is not letting me get my money out why is that ? My app is showing 2000 still on my card but when I try to get 400 out on a ATM it says 0. Why?

I have a TurboTax account for my TurboTax credit card and it is saying that I have 2,000 still in my card but when I try to pull out 400 from the ATM it says I have 0 in my account but when I go check on my app it says I still have 2000 why can I not pull out money from my TurboTax credit card?
