Wondering about opening wallets across different programs?

Hi, I am not very tech savvy but I have some Bitcoin. I've had a few different wallets over the years.

Well, I want to finally get organized. I decided to just open everything using my seeds on Wasabi. Most of these were wallets I initially created and used using Electrum. So it looks like I have all my wallets recovered, and they all seem to be zeroed out except one.

That seems right to me, I'm pretty sure I moved everything into the one wallet, but I'm wondering if there's any other steps I should take to make sure I am seeing the right balance. If I just entered the seed correctly and it came up with a wallet, that's correct, right? There's nothing else I need to do?

I want to just stop using all the older, empty wallets and get rid of the seeds connected to them, which I have written on paper copies that are currently just cluttering up my desk. Just wondering if there's anything else I have to do to make sure I am checking my balances accurately before retiring these wallets for good.

Feel free to make fun of me for being disorganized, you wouldn't be wrong!
