I am not an accountant or tax prep person. You should ask your accountant to verify.
Yes, you can claim any verifiable expenses and end up with a loss. Schedule C instructions for Line 31 (page C-13) notes
Figuring your net profit or loss. If your expenses (including the
expenses you report on line 30) are more than your gross income, do
not enter your loss on line 31 until you have applied the at-risk
rules and the passive activity loss rules. To apply these rules,
follow the instructions in Line 32 and the Instructions for Form 8582.
After applying those rules, the amount on line 31 will be your loss,
and it may be smaller than the amount you figured by subtracting line
30 from line 29.
The caution further down notes
If you enter a loss on line 31, you may have an excess business loss.
Use Form 461 to figure your excess business loss.
Follow all those instructions, and you should be good. I would not try to go for business use of home or other potentially questionable expenses. Personally, I'd only include what I had verified receipts and documentation (e.g., business use of vehicle) that can be easily proven.
