Thanks for getting in touch with us today. I can add a bit more about adding the state information on the 1099-MISC.
My peer @Kristine Mae shared a great answer. Being able to report your state information to the 1099-MISC form in QuickBooks is a great idea we can add in QuickBooks Online.
Since you're unable to do this in our, you can try the workaround you've added on your post. You can also download the 1099 MISC from the IRS website then fill it out manually.
I would also recommend sending a request to our developers using the Feedback option. Doing this will let them know what features would help a business like yours run a little better, and they will consider that in a future update.
Here's how to send your request:
1. Click the Gear icon. 2. Select Feedback. 3. Enter your feedback and suggestions. 4. Click Next. 5. Select Feedback for the Category. 6. Click Send message.
