How can I set my LLC account as the primary payout on a new store?

[TerrenceW]

Setting up a new shopify store and the payout has "Shopify balance account" listed. It then says to change the payout account I must enter the new information as well as the old information that I have never listed at all. Any help on how to get my LLC account with routing and checking added as the primary payout account?  Thank you in advance if you can help here.
