Hi Cassie_T,
Thanks for your questions. I can see why you're asking if those sales returns and allowances need to be linked to any account.
You don’t need to link the Sales Returns and Allowances account to the original invoice.
Once you save the negative invoice, go to Sales > Sales returns and credits, choose the return, then click Refund. Select the bank account and record the refund.
The extra $0.01 is likely from GST rounding. Adjust the line amount slightly so the total is exactly $258.00. If you’re unsure, check with your accountant.
