In general, I agree with @Bsch4477 in that most expenses incurred in a hobby are not deductible as they are typically defined as itemized deductions. This became effective beginning in 2018.
However, Publication 535 page 7 states the following:
You can determine gross income from any not-for-profit activity by subtracting the cost of goods sold from your gross receipts. However, if you determine gross income by subtracting cost of goods sold from gross receipts, you must do so consistently, and in a manner that follows generally accepted methods of accounting.
As a result, you can report your sales income less your CGS on Schedule 1 line 8i.
Make sure you maintain meticulous records, as should you be audited, the IRS will definitely focus on this issue.
Since this forum is limited in the ability to gain insight into your activity, being able to provide much more assistance will be beyond the scope of this forum.
Edit: Not sure why @AmeliesUncle reply was not showing up when I responded, but we do reach the same conclusion.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
