How to Edit GSTR1 After Submission

This discussion addresses the possibility of editing GSTR1 after submission but before final filing. Participants confirm that once GSTR1 is submitted, even if not finally filed, it cannot be directly amended. Errors, such as incorrect HSN-wise data, must typically be rectified in the annual return. There appears to be no provision for making changes to a submitted GSTR1 in subsequent monthly or quarterly returns.
