You can't merge account due to security issues. You should use the same account each year so that your previous years tax data is available. If you use the same account each year, your information will carryover and will be pre-populated which will save time and prevent typos.
There is a way to get a list of all of your TurboTax accounts and I will leave the link below. Once you find the account you used last year, use that one for this year and all future tax returns.
How many Intuit accounts do I have with TurboTax?
