Itemize donations makes sense only if their amount is above standard deductions, cotrect?

[JamesG1]

Yes, in the vast majority of the cases.

However, itemized deductions is a requirement if married taxpayers file married filing separately.  If one taxpayer itemizes deductions, the second taxpayer must also itemize deductions.

Then it does seem to have much sense to make small donations if they are below standard deduction? No tax advantage then.

Correct.   On next year's tax return, those that use the standard deduction will be able to make a tax deductible cash donation of $1,000.
