My tenant paid a check and the check was return from my bank. I asked her to pay me but she told me that the check was cash from her account. She opened a case with her bank but not hear back yet. I asked her to pay but she told me to wait.

Give her a pay or quit notice.

You don't care what she told you and you don't care, sorry but she most likely is lying, has she shown you where it was paid ?

But you give her a notice to pay ( plus any fees the bank charged you) or she will be evicted.
