I have three children i want to claim for EIC, but my only income was personal sales of crafts and goods out of my home. Am i able to claim this income and file a return?

i have three children under 18, i have always qualified for EIC before, but this year i did not work outside of the home. my only income was child support, SSI for one child, and sales and tips that i made off of selling products and goods out of my home. I probably made a few hundred dollars this way, but because i never imagined i would possibly make enough to claim or do something with, i didnt keep great invoices in the beginning. Can you give me any insight on how i can still claim the EIC for my children?

thank you
