I did my taxes on one account a few years ago. With my other taxes, I did those within these past couple years. I may need some help putting them into one account.

I may have forgotten my account info from the few years ago. I've made another account to do my taxes with. With this second account, my taxes have been denied multiple times... My concern is if everything that I've done within the 2 accounts should only be put into one account so everything is in order and nothing should be denied again.
