Hi yosemitedoran,
Welcome to the Support Communities! If I'm understanding your question ... your daughter has two different Apple ID's? If so, she can't use iTunes Allowances on the Apple ID she is using for Family Sharing.
Start or join a family group using Family Sharing - Apple Support

One adult in the family—the family organizer—can set up Family Sharing for the group. When you set up Family Sharing, you'll be asked to confirm that you agree to pay for purchases initiated by the family members you invite and that you have a valid payment method on file. Valid payment methods for setting up Family Sharing include credit cards and debit cards.

If you use Family Sharing and Ask to Buy is enabled for your account, you can't buy iTunes Allowances.
For the Apple ID that is not part of Family Sharing, this is a possible option:
Set up your Apple ID for iCloud and iTunes - Apple Support

First, copy all of your purchased content so that it's on the same Mac or PC with iTunes. This computer should be the one you sync your device with.
Next, authorize your computer to play content with each Apple ID in iTunes. After your computer is authorized for all of your content, it can be synced to your iPhone, iPad, or iPod touch.
I hope this information helps ....
