Hi all, 

Regarding the links that Marnina put up - we recently moved to a new Community site, and some of the content has been changed from that migration. Sorry for the inconvenience with the broken links!

If you have lodged your BAS already, any changes you have made to that period since the lodgement will automatically appear as amendments/adjustments to that BAS. You can see these in a list in the GST Amendment Report under the Reports section.

You can also have your BAS unlodged if you want to adjust the BAS amount without making amendments. Simply contact our support team and we can get it unlodge for you: https://quickbooks.intuit.com/au/contact/.

Hope this helps!
