Hi Raymond,
Thank you very much for your comment.
The transactions that were recorded in QB are the following.
These transactions are recorded using manual Journal entries.
In Dec 2020 (To include the unpaid expense in 2020 that should be recorded as Dec 2020 expense)
Dr. Professional service fee $20,000
Cr. Accounts Payable $20,000
In Jan 2021 (To record an actual payment to this vendor)
Dr. Accounts Payable $20,000
Cr. Cash $20,000
So the actual payment is made in Jan 2021, since the expense is recorded in Dec 2020 I cannot include this amount in 1099. (This amount was not included in 1099 last year either)
Is there any way I can correct this problem? If I can't figure out via Quickbooks online, I'm considering using the Standalone Intuit 1099 E-file service but I'm not sure if it is possible when I already use QB Online for bookkeeping.
