Deductions & credits

Hi,

I worked with the NHS, and my pension is fully government-funded and taxable only in the UK. However, completing Form 1099-R increases my tax amount because it lacks a box for foreign tax paid like Form 1099-DIV. This raises my IRS tax by about $4000. How can I request credit to offset this?

Thank you for your help.

Sincerely,

NI
