My daughter is 18 and graduated from highschool in June of 2022 still living at home did not enrolled in college in 2022 or earned any income in 2022 can I claim her?

Yes.

There are two types of dependents, "Qualifying Children"(QC) and Other ("Qualifying Relative" in IRS parlance even though they don't have to actually be related). There is no income limit for a QC but there is an age limit, student status, a relationship test and residence test.

A child of a taxpayer can still be a “Qualifying Child” (QC) dependent, regardless of his/her income, if:

1. He is under age 19 (on December 31 of the tax year), or under 24 if a full time student (high school counts) for at least 5 months of the year, or is totally & permanently disabled
2. He did not provide more than 1/2 his own support. Scholarships are excluded from the support calculation
3. He lived with the parent (including temporary absences such as away at school) for more than half the year

Graduating from high school in May or June satisfies the 5 month requirement for being a full time student for the year. So, even if she works the rest of the year, she is still your qualifying child for 2022.  Also, if she is still under 19 on 12-31-22, she is a QC even if not a student.

So, it doesn't matter how much he earned. What matters is how much he spent on support. Money he put into savings does not count as support he spent on him self.

The support value of the home, provided by the parent, is the fair market rental value of the home plus utilities & other expenses divided by the number of occupants.

The IRS has a worksheet that can be used to help with the support calculation. See: http://apps.irs.gov/app/vita/content/globalmedia/teacher/worksheet_for_determining_support_4012.pdf

How old will your daughter be on Dec 31, 2022?  That matters. If she will be "under the age of 19" on that date, then assuming she meets the other requirements, she's your dependent. (It doesn't matter how much she may earn during 2022 either.)
