Do I enter alimony recived as income.

Yes.

Support payments (alimony) are taxable to the recipient and deductible to the payee so they are entered as income for you.

Child support payments are not taxable.

Regarding  Alimony:  Under the TCJA, Alimony is no longer deductible  by the paying party, nor tax taxable to the recipient for agreements entered into after 2018.  Child support payments are also not deductible by the paying party.
