I believe you are referring to the Total Submission Storage.
The Total Submission Storage is the total number of all submissions stored in your account. It is not referring to the monthly submissions. For example, you received 100 submissions monthly for 5 months, then your total submission storage is 500.
Under the Free plan, you can only store 500 submissions. Once you reach the limit, our system will automatically delete the oldest submission so the new submission can enter.
I would suggest you download or export your submission to avoid losing it. You can delete some submissions in order to free up your submission storage. Here's a guide: How-to-Delete-Form-Submission-Data.

Hope that helps. Thank you.
