GSTR 1 outward supply query

While filing 2nd quarter of GSTR 1 returns we have missed out of July and Aug sales details in GST 1 returns and only sept month sales was taken in the returns. In 3B all three months sales were taken on monthly.

so, how to rectify this mismatch to declare both of month of sale of July &Aug'20 in GSTR1.

Kindly suggest how we can resolve this changes.

Quick Summary
This discussion addresses a common GSTR 1 filing error where sales for July and August were omitted, while September sales were correctly included. The user correctly reported and paid taxes for all three months in GSTR 3B. The advice given is to include the missed sales in the next GSTR 1 filing. Since the tax was already paid via GSTR 3B, no additional liability or interest is typically due, although the customer's input tax credit will be delayed until the next quarter.

File in next month Gstr1 and pay his liability with interest
We have showed correctly in 3B and made the tax payment but we missed two month sales only in GST 1 rather than adding 3 months sales.
so how liabilities will arise? apart from interest
Add those months bills in next quarter.
customer Will get credit only during the quarter.
no need to pay interest since u reported those bills in 3b and paid taxes.
Correct but due to recent changes in the Portal the sales reported in GST 1 will also automatically reflect in 3B in this case does the portal show any negative alert since adding those month sales in GSTR 1.
If GSTR 3B - Correctly filed , disclosed missing invoice in suceeding months return !

Sorry no liability for you doesn't seen 3b part

Thanks you all for your comments
