This is a public forum, so for your security I have removed your user IDs. It is possible, and common, to have multiple accounts with TurboTax; however at this time we cannot merge those accounts.
What you can do is download and save your tax file so that you can upload it to the account that contains your past returns. For instructions, take a look at this FAQ. https://ttlc.intuit.com/replies/3300420
