Daughter is 20 yrs old & doesn't qualify as my dependent because she earned more than $4150 in 2018. Should I erase her from my return & let her claim herself on hers?

Yes, you should delete her from your return since she does not qualify as your dependent this year. However, if she was a full-time student for five months during 2018 then her income amount does not matter and you may qualify to claim her as a dependent.
