Don´t know how to log in on a second account on my laptop

Hello,

- I'm mostly on the computer and not on the phone.

- I have a functioning main Insta account (MIA) that I use via an automatic login on the laptop.

- Furthermore, there is a second account that was once generated on an experimental basis, which I would like to delete (but I am never quite sure from the descriptions whether this is actually deleted and not the (MIA) during a deletion process).

- Now I have created a required third-party account (TPA) (i can see all accounts on my cell phone + laptop), but I don't know how to log into it on the computer ?!? THAT IS MY QUESTION!!! WHAT do I have to do to be able to log into the (TPA)?!?

The Google conglomerate of help is nowhere correct and is annoyingly foggy confusing (for a relatively inexperienced Instagram cell phone user)!
