If you were expecting your refund direct from the IRS, and Chime bounced it back, the IRS should mail a check in about 4 weeks.
If you used refund transfer to pay your Turbotax fees, and TPG sent the remaining refund to a closed Chime account, then Chime bounced it back to TPG. I would call TPG and inquire. They might be able to send your refund to your new account. If not, TPG must bounce it back to the IRS, but that seems to take longer than if you were expecting a direct refund.
