Hi @melindajamulis,
Do you have Discord ? The best would be to come on https://discord.me/share2steem so we can provide you support. If not, I can do it here but I need more information.

You linked the wrong account -> So you couldn't verify it I suppose, that's not really a problem, I can remove manually from the list of your accounts. You can add as many accounts as you want and as long they're not verified and active, simply linking an account doesn't imply anything (nothing will be cross-posted and so on)
You're unable to verify your Instagram account -> Did you link it ? Why can you not verify it ? What's the error message displayed on the website ?

Thanks
