I have the emerald card from H&R BLOCK will my refund go on there? From the stimulus refund

Yes and No
If you paid for your tax preparation at the office and did not have your refund process through H&R Block Bank (refund anticipation check) or HSBC Bank (refund anticipation loan) than your rebate will be directly deposited to your Emerald Card which is in essence your bank account.
If you had the preparation fees withheld from your refund and/or paid a finance charge to receive your refund quickly (in the form of a loan) then your rebate will be mailed to the address that is on your tax return.
The Reson behind this : when you use a bank product to receive you refund for whatever reason, the money is directly deposited into a temporary account that has been set up for you. Once it is in that account it is immeadiatly withdrawn and redeposited into up to 3 different accounts depending on the bank product you chose. That account is then closed and the IRS cannot deposit money into a closed account.
If you got a refund anticipation check (8-15 days, not a loan) the money was disbersed between H & R Block (to pay for the preparation of your taxes), the bank that holds the account (account origination fee) and your Emerald Card (your bank account).
If you got a refund anticipation loan (1-2 days -or- instant) the money was disbersed between H & R Block (to pay for the preparation of your taxes), the bank that holds the account (account origination fee) and the lending institution that you borrowed the money from. Not sure how you filed ? Look in your tax papers for your Block Advantage Report. The first page shows all refunds and balance dues. Your preparation fees and bank fees (if aplicable) are also listed. No bank fees means your rebate will be on your card. If you had bank fees then your rebate check will come in the mail.

Is there a way to find out if account is closed?
