How likely am I to be stopped at the border if I visit Canada and come back? TN Visa succeeded after 2 failed attempts (Data Engineer)

I had a very hard time getting my TN last month due to having an Electrical Engineering degree and doing a software engineer role.

Denied twice at Blue Water Bridge (and yelled at as well as insulted for wasting their time by trying a 2nd time there despite a whole new package which they didnt even glance at).

Then I went to YYZ as a last ditch attempt before giving up and they gave it to me without a single question.

I feel like I got very lucky, mind you I did go to a lawyer and put a lot of work in showcasing the job as more data design engineering, but still. It left a sour taste in my mouth due to my bad interaction with a very angry border agent with a stick up her ass. Now I'm scared of visiting home and having to cross the border.

Is it likely I'm going to get stopped or get my TN stripped? While I do believe I deserve my TN as my job is very much engineering data system design work, I could also easily see someone viewing it as software engineering and rejecting me for not having a software or computer engineering degree. Is this likely to be checked and looked at if im just visiting home and coming back?

Any advice appreciated!
