Single family rental house owned for 20+ years and fully depreciated. Hailstorm last spring necessitated replacement of entire roof. Insurance covered all but $200 of costs (Roofer $5400-5200 Insurance Co). I have read and re-read Form 4684-Casualties and Thefts and Instructions. I'm at a loss on how to complete SECTION B—Part I Lines 20 on. My attempt using TaxACT:

Line 20-adjusted property basis... zero(0)
Line 21-Insurance/reimbursement... $5200
Line 22-If gain (21 > 20 I'm done?

Where is the repair costs considered?

What am I missing?
