My oldest son is 18 yrs old not in school but did have a job for a few weeks has a w-2 has lived with me the whole time whow do i claim him and his w2 or do i or what do

You can claim him up to the age of 19 no matter how much he made just like you always did in the past.

However, his W-2 will be reported on his return if he is required to file or if he wants the withheld taxes refunded BUT he must NOT claim himself.
