I got a tax topic 151 which I know what that is but will they hold my entire refund or give me a partial that was not affected? The affected part I’m sure was my step son

I have three children 2 of which are my biological kids but my son is my step son. I’m sure that’s why I got a tax topic 151 to prove he lives with me. But I was wondering if I would get a partial or my refund of the part of the refund that is not affected which would be my other 2 kids?
