Sent Doge to wrong sender

Hello I withdrew dogecoin from my BianaceUS into my trust wallet. I tried resending the dogecoin back to my bianace. I copied the senders address and sent it back. However I never received the deposit in my bianace account. I think I sent to the wrong address.

I sent the wrong type of Dai coin to another wallet yesterday and I can’t find out how to fix it for the life of me lol. I didn’t realize there were 3 types of Dai coin in trust wallet and now I feel like I just lost my money I sent.
