Status Change from Spouse to Primary Filer in 2020

In 2019 and all prior years, I filed Married Joint.  My husband died in 2019 so 2020 going forward I will be filing single.  Since the primary SSN and filer was my husband, I've been told that I have to establish a new account for 2020 forward with my SSN as primary.  Will any information from my 2019 TurboTax file carry over to 2020 or must I start as a new filer?
