State tax filing

This is my first time filing a D-30.  My DC taxable income for my rental property is -12,000.

 

Am I completing the following correctly on the D-30 form?: 

  • Line 37(Tax) 8.25% of Line 36 (Taxable income):  Do I put in - 990?   Or do I put 0? 
  • Line 40 (Tax): Do I insert the minimum tax of $250? Or leave blank?
  • Line 45 (Total amount due): $250
  • Schedule F:  Do i have to complete this? the rental property is 100% in DC. If i have to complete what do i put as gross receipts?
  • When submitting my tax returns do i have to include schedules and documents that are empty? for instance Schedules I and J, Combined Group Schedule, Worldwide combined reporting form?
  • Schedule SR - I understand that the tax credit is inapplicable because my net income is a loss. Please let me know if my understanding is correct.

Thank you so much for any help!
