SMART stats shows it's at 54% health remaining, all tests passed without errors.

The drive might be too old to report back TBW. It's a Crucial 256 GB SATA 3.1 SSD.

It has LBAs written which is 138292009426. The sector size is 512 bytes.

I think you can calculate TBW from that?

(138292009426 * 512) / 1000000000000 = ~70.8 TB written?

Yes, and I have 250GB Evo Samsung with similar stats, of same age and power on time.
