side hustle’s deductions exceed its income

i have a w2 job and i do freelance work on the side. by the end of this year, i probably will have only earned $1k with the freelance work (last year was much higher, but oh well it be like that). however, i have been taking non-university foreign language courses and went to a networking event this year, both for that freelance work. the freelance gig requires networking and that foreign language to get more work. that has probably come out to $2k spent.

my question is, what happens with that excess deduction? does it affect the w2 job's income taxes when i file next year?

thanks!
