Welcome back to the thread, Miram2022. I'll be providing details on how converting an accountant's copy works with a standard version of QuickBooks Desktop. Then, to ensure you're able to perform the process by following the steps below.

When converting Accountants copy to a regular company file or QuickBooks premier edition, you'll have to make sure that Accountants' Copy and QuickBooks Desktop versions are compatible. 

Then, when performing the process of converting, you'll have to use the same year of QuickBooks Desktop to avoid any issues. However, you can still work on the Accountant's Copy using a different version as long as the gap between the versions is just one year. With this, you can convert the Accountants copy 2022 to your 2021 Premier edition without purchasing another one. 

To start with, you'll have to secure a backup copy of your company file so you can restore your file in case you ever run into a problem with your data.

Once done, you can now begin following the steps below on how you can change the accountant’s copy to a regular company file in QuickBooks Desktop.

Here's how:

1. Go to the File menu. 
2. Choose Send Company File and Accountant's Copy.
3. Select Convert Accountant’s Copy to Company File/QBW.
4. Click OK to confirm you want to convert the file.
5. Open the folder you want to save the .QBW file in, and rename the file. 
6. Choose Save. Then, select OK once you’re done converting.

After that, you need to re-enter any changes you made to the original company file after creating the accountant’s copy. Then, you can no longer import an accountant’s changes (.QBY).
