How do I merge a contractor.

Hello there, @tfcnyc.

Ideally, you should be able to merge your contractors by following the steps shared by my colleague above. Since you're unable to do so, I'd suggest logging into your QBO account via an incognito window. This feature doesn't use the existing cache files, which makes it a good place to determine if there's an issue with the browser. 

Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P 

Once signed in, go back to the Expenses menu and merge the contractors from there. If it works, let's clear the cache of your main browser. This helps remove its stored cache so it'll function efficiently.

However, if private browsing doesn't work, I recommend using different browsers. For more details, see this article's Supported browsers section: System Requirements For QBO. 

For more details on how to merge your contractors, check out this article: How to merge accounts,customers, and vendors.

Also, may I ask if you encounter any errors while merging your contractors? Any additional information is highly appreciated.

In case you need to prepare and file your Federal 1099s, I'm adding this article for you:  Prepare and file 1099s.
