Line 19a

If you made payments to or for your spouse or former spouse under a divorce or separation agreement entered into on or before December 31, 2018, you may be able to take this deduction. You can’t take a deduction for alimony payments you made to or for your spouse if you entered into your divorce or separation agreement after December 31, 2018, or if you entered into the agreement on or before December 31, 2018, and the agreement was changed after December 31, 2018, to expressly provide that alimony received is not included in your former spouse’s income. Use Tax Topic 452 or see Pub. 504.
