She is adorable! Does she have a name yet?
I've attached a few helpful links that may help with your question
The first one is just a good read for owners of female budgies. The second and third discuss introductions and dynamics between multiple birds.

As for helping her feel more comfortable, playing background music or TV (NOT bird sounds as this can make birds feel more stressed looking for "the other birds") is essential as silence equals danger to budgies. New and settled-in budgies alike can get great comfort from having background sounds. Talking to her as much as you can, and reading to her will also help her realize she is in a safe place.
The links above cover this, but it's important to introduce them in a neutral territory, where the time comes. A room unfamiliar to both of them may help so that Snowy doesn't feel any type of territorial behavior. Gradual introduction is also usually best, unless the budgies themselves seem to be immediately taken with each other. Spending a few days next to each other in separate cages is a good idea so they can get to know each other without the stress of suddenly being in the same space and having to sort out a pecking order.
Of course, as you mentioned, these introductions can only start after your new little girl has quarantined and/or is cleared by a well-birdie checkup, so during the time that you wait for that as well you can spend lots of one-on-one time with each of them
