1099-K for sending/receiving money NOT INCOME

Hi. I regularly send family (and sometimes friends) money ($25 min up to $1,000 max) through Zelle, CashApp, and Venmo. Do I have to pay taxes on my own money that's sent as a gift or to pay half of a joint bill or even from one account to another at a different institution? I do not receive money appropriated as income via these apps. I assume I will receive a 1099-K but since it's not income-related, how do I file so I WILL NOT be taxed on it?
