It might or might not be enough, but if that's the total amount that was withheld from her pay in 2022, then it's right for the W-2. Check against her final pay stub for 2022 if you have it.
Are you looking at the actual paper W-2 from the employer, or did you import it into TurboTax or upload a picture of it? If you imported it or uploaded a picture, make sure that the amounts in TurboTax match the actual W-2. Mistakes sometimes occur in importing or uploading.
If you want to make sure your wife's withholding is correct for 2023, you can use the Tax Withholding Estimator on the IRS web site to figure out what you should each put on the W-4 forms that you give to your employers. She can give her employer a new W-4 if not enough is being withheld.
