Taxes due for hobbyist Group Buy
You do actually have some profits (whatever is left from donations). The way it goes is that you report everything on your Schedule C. You will report this: Your gross profits will then flow to Net Profit (line 31) since you had no other expenses (unless you had some other expenses, like paypal fees, which will appear in the relevant category in part II), and from line 31 it will go to your 1040 for the final tax calculation.
