My state refund is higher than my federal. Why is that?

It is possible for that to happen, depending on the kind of income you entered on your tax return, and on the amount you had withheld from your income for federal and state taxes.  It is also possible that some of your forms are not ready and you should not trust the calculations at this point.  Due to the massive tax law changes, new forms, and new tax software, many federal and state forms are still not ready.  Click on "Review" and you will see which forms are not yet ready.  It is too soon to file--even if the software will allow it.  The IRS is not accepting returns yet--and has not yet announced when they will begin.  It is unlikely to be sooner than the end of January or even later.  Wait until all of your tax documents are in order--many will not arrive until later in January or early February, and until the forms are all finalized.
