Time machine split my drive into two volumes/partitions

Britt3588,

As you've seen, this is because Disk Utility is showing two drives as you mentioned. They wouldn't be seen as partitions but completely separate drives (or volumes in this case).

At the top of Disk Utility, you'll see there's a Volume with a + and - sign. Try highlighting one of the drives and see if - is clickable to remove it. This link goes into these steps in a little more detail: Add, delete, or erase APFS volumes in Disk Utility on Mac - Apple Support

Take care.

Enlarge a partition on a storage device

If you have multiple partitions on a device and one of them is running out of space, you may be able to enlarge it without losing any of the files on it.

To enlarge a volume, you must delete the volume that comes after it on the device, then move the end point of the volume you want to enlarge into the freed space. You can’t enlarge the last volume on a device.

WARNING: When you delete a volume or partition, all the data on it is erased. Be sure to back up your data before you begin.

1. In the Disk Utility app  on your Mac, select a volume in the sidebar, then click the Partition button .
2. If Disk Utility isn’t open, click the Launchpad icon  in the Dock, type Disk Utility in the Search field, then click the Disk Utility icon .
3. In the Apple File System Space Sharing dialog, click Partition.
4. In the pie chart, select the partition you want to delete, then click the Delete button .
5. If the Delete button is dimmed, you can’t delete the selected partition.
6. Click Apply.

We hope this helps.
