I sent an application for renewal of TPS with amount of $515. I got my application back with I-797C saying :

"The payment amount is incorrect , or has not been provided. Please review the form instructions for the fee information. Please resubmit the application/petition with the appropriate fees to the address listed on the bottom of the page."

Also,
What should I put my current status? Last time I filled TPS, I was on F1. Should I mention my current status as F1, or TPS.

Please help. I would appreciate the information.

Thank you in advance.
