Based on the instructions for line 10b if you do not itemize on schedule A you are permitted to take $300($150 married filing separate) to a qualified charity.
Here is the excerpt from page 29 of the 2020 Form 1040 instructions.
Line 10b
If you don't itemize deductions on
Schedule A (Form 1040), you (or you
and your spouse if filing jointly) may be
able to take a charitable deduction for
cash contributions made in 2020.
Enter the total amount of your contributions
on line 10b. Don't enter more
than:
• $300 if single, head of household,
or qualifying widow(er);
• $300 if married filing jointly; or
• $150 if married filing separately.
The contributions must be made to
organizations that are religious, charitable,
educational, scientific, or literary in
purpose. See Pub. 526 for more information
on the types of organizations that
qualify. A deduction can't be taken for a
contribution to an organization described
in I.R.C. 509(a)(3) or for the establishment
of a new, or maintenance of an
existing, donor-advised fund. Also, contributions
of noncash property and contributions
carried forward from prior
years don't qualify for this deduction.
See the Instructions for Schedule A and
Pub. 526 for more information on those
types of contributions.
