BLOCK will produce a .taxfile ... how do you think their program transfers in the prior year information ? What you need to do is get that .taxfile and if you cannot then either don't switch programs or suck up and make the manual entries.
FYI ... if your AGI is $73K or less you can try one of the IRS FREE FILE options : https://www.irs.gov/filing/free-file-do-your-federal-taxes-for-free
