Deductions & credits

Let’s assume I didn’t have ANY income this year but only expenses. Can I write them off somewhere? I wrote them off last year when I created new line of work on turbo tax. If I am doing the same this year turbo tax still deduct those expenses from my total income. Can I continue doing it? Again, those are not related only to the W-2 specific gigs.  Those are regular expenses I have yearly for this line of work.
