My bill is negative.. (Previous balance $148.53) (deposit return -$100.00) (new charges -$74.86) (total due -$26.34) so do I pay more next months bill or will $26.34 be taken off my next bill? An it says my account is past due?? I'm confused!

I'm just not sure if I have to pay an extra $26.34 or will it be taken off my next bill. And it says pay it immediately.. But how??
