Since the debit card is given to you personally, and the unemployment benefits are paid to you personally, and your personal finances are being kept in a separate Manager “business,” that reinforces my earlier comment: you should not enter the unemployment benefits in Manager in any way.
If you use the debit card to pay for a business expense, enter an expense claim in Manager for the business. That constitutes an outside entity (you, not your business) paying for a business expense. See the Guide: Use expense claims | Manager.
Now, in your personal finance “business,” the weekly addition of unemployment benefits to the debit card is just entered as a receipt. For the bank account, choose the debit card, set up as a regular bank account, not a credit card. The plastic card effectively holds the monetary asset instead of some financial institution.
