Review the entries you made in the mortgage interview in the Federal return. You can revisit your entries in the mortgage interest questionnaire to confirm, for example, that you identified the loan as being secured by your home, that the loan funds were used to purchase or improve your home, the dollar amount of interest entered was correct, and that the loan principal was entered and didn't exceed applicable limits ($750,000 for loans originated December 16, 2017, or later).
Then, review any entries you made in the California interview for any items treated differently in California. California allows interest on home purchases up to $1,000,000, whereas the Federal return currently limits the purchase price to $750,000, so it is not typical to see a larger deduction for the Federal return.
You could also opt to delete the California return and then complete it again after you check over your Federal entries.
