my chapter 13 I made payments on credit card was not suppose to am I in trouble with court what should I do

The entire purpose of Chapter 13 is to use the Chapter 13 plan to resolve ALL debts that existed up through the date you filed your petition.

You didn't mention whether you had an attorney or not. I assume you do as Chapter 13 is so complex that it would be exceptionally difficult for an individual to handle it without the assistance of qualified bankruptcy counsel. Assuming you do have an attorney, you should advise him or her of this right away.

That being said, you are not supposed to pay your creditors directly. However, the fact is that you made the payments voluntarily, and your creditors did not do anything wrong by accepting them. If the amounts involved are nominal, I would just write this off. To get involved legally to try to undo the payments would probably be much more involved and costly than would by worthwhile. You would not notify the court about this.

Also, since you are in an active bankruptcy, creditors would not want to respond to your letters since you probably have an attorney representing you, and also because they don't want to be accused of violating the stay.
