Received this message "yearly storage limits"

Hello, I received this message " You have reached your yearly storage limits . Please upgrade your plan or purchase an add-on to increase your usage limits."
I can’t afford to pay anything,
If I want this message to be deleted, can I delete some of the forms and that will work or do I have to create a new account?
If I continue to work on the same account, will this lead to deleting some forms or closing the account??

Welcome back to the community, @Sira! You can always check your submissions/storage usage under ACCOUNT SETTINGS>Usage. You can then upgrade your account to a desired paid plan from under ACCOUNT SETTINGS>Plans.

Feel free to reach us through for any queries related to your account upgrade. We would be happy to help you out there.
