The system concluded that I have $1800 federal refund from the standard deduction. However, I'm not qualified for it as I'm filing "foreign exclude income".

There wasn't an "none of that apply" option on the page of "Standard deduction".

All taxpayers, regardless of the type of income, get the Standard Deduction on a federal tax return.

The total of all your itemized deductions on Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.

Standard deductions for 2020

• Single - $12,400 add $1,650 if age 65 or older
• Married Filing Separately - $12,400 add $1,300 if age 65 or older
• Married Filing Jointly - $24,800 add $1,300 for each spouse age 65 or older
• Head of Household - $18,650 add $1,650 if age 65 or older

A Refund of $1800 sounds like the stimulus credit on line 30 of the form 1040 and has nothing to do with the standard deduction or the exclusion of the foreign income.   If you did not get the stimulus in advance then you get it on the tax return if you qualify.
