How about Federal tax? If yes, where do I enter it?

This is a California-only credit. There's nothing like that in the federal return.

Could the rent be put in my itemized deductions on my 1040 form?

There is not a rent deduction or credit on your Federal return.  If your state has anything for renters you will be prompted to enter your rent info when you complete your state return.  As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, Rhode Island, Vermont, and Wisconsin. I don't know if there are any others.

Where do I enter my space rent on my taxes for the year

Where on the CA tax form is this supposed to be noted?

So, the qualifications for Rent’s Credit in California is income of $42,932 or less. If I make more, saying I don’t work for McDonalds, all the money I paid in mobile home rent space is nonsequential?  

Yes. You will not get the Nonrefundable renter’s credit if you made more than $43,533 (2020) filing single or married/RDP filing separately or $87,066 (2020) if you are married/RDP filing jointly, head of household, or qualified widow(er) so all the money you paid for mobile home rent would be inconsequential for the renter's credit.

 

The other requirements are:

• You paid rent in California for at least 1/2 the year
• The property was not tax exempt
• You did not live with someone who can claim you as a dependent
• You or your spouse/RDP were not given a property tax exemption during the tax year

The credit is $60 for single or married/RDP filing separately and $120 for head of household, married/RDP filing jointly or widow(er).

There is one catch to the general answer "yes" to this question. If you own your home and pay property taxes on it, and get a Homeowner's Exemption that reduces your property taxes, you can't take the Renter's Credit. For example, I get a Homeowner's Exemption on my mobilehome, of $7,000. With the local property tax around 1%, I save $70 on my property taxes, slightly beating the value of the Renter's Credit. Whoo whoo!
