I just had the same scenario.  I dont have the PS Fixed Asset module to track depreciation, so I did this:  .  I drafted a 1041 as usual "as if" it were a non-grantor trust.  Then I "Saved as" this file as the file that became my filing copy - in this new file, I changed the type of trust to a Grantor trust and populated the Grantor worksheet using the data generated by the first file, which became my "dummy file" for tracking depreciation going forward.  As long as I remember not to file my dummy file with the IRS I should be OK - Ha!
