Can I file short form for a relative that passed away on 01/04/18? She did have income and paid income tax for the month of January.

Yes, you can file a Tax Return for your relative. You will need to set up a separate account for this Tax return.  

There are no longer any "short" forms. Starting in 2018, everyone uses the same Form 1040, which also includes new Schedules 1 thru 6.

As you start the TurboTax interview for your relative, under the Personal Information section,  you should choose "I'm preparing this return for ______ who is deceased".  Next, you should enter the date of death. From here you can prepare his return as you normally would.
