Oxford university doesn’t teach us these basic tenses.

The correct translation of any one having something in the past in positive, negative, and both interrogatives is as follows.

I had a good job.

I did not have a business. (I didn’t have a business)

Did you not have a business? (Didn’t you have a business?)

Did you have a good job?

I have named these tenses Past simple in my ‘Marvelous English Speaking Course (part 1) book

REMEMBER: these are completely different from PAST PERFECT TENSES, where ‘had not’ is used instead of ‘did not have or didn’t have’.
