Deductions & credits

Also, the Tax Guide states the credit would be applied to foreign income. My sole income is from the USA, but is being taxed in the UK per the tax treaty. Supposedly there is a way to "resource" the income to be considered as UK income and, thus, eligible for the credit. How do I do that in turbotax? It would be with the 8833 form, which TT doesn't handle, correct? I'd have to print out the return, manually add the form, and mail it in?
