Hi there, @ppersonious.

Let me help you fix your issue with your check alignment. We'll need first to update your QuickBooks Desktop for Mac to the latest release.

Then, we can now run the verify rebuild tool to detect issues with your check alignment.

Here's how: 

1. Select File, then select Utilities.
2. Press on Verify Data.
3. Hit on OK to close all windows. If you see “Your data has failed the integrity check” you need to rebuild your file. If there are no problems with your data, you’re done.

Afterward, proceed with verifying the data:

1. Select File, then select Utilities.
2. Press on Rebuild Data, then select OK to close all windows.
3. QuickBooks will ask you to make a backup before rebuilding your company file, select OK. If you don’t want to do a backup, select Cancel to continue rebuilding your company file.
4. Once the rebuild's finished, select OK.

Feel free to read this article for more details: Verify and rebuild data in QuickBooks Desktop for Mac.

Let me know how it goes. I want to make sure that you're all good. Keep safe!
