If you inherit an IRA from your deceased spouse, you can roll it over into another retirement account without any tax implications.
Once you withdrew it, it became taxable as ordinary income. If you were under 59 1/2 you would also incur a 10% penalty.
You should have received two 1099-R's. One for your spouses IRA that you rolled over, and one for that account that you closed out.
The rollover is not taxable. The withdrawal is fully taxable.
