@aaron5596 ,
How are you receiving K-s from your business in Poland -- thought the Ks are issued ONLY for US persons and generally living in the USA.
Never the less -- for 2022 -- you show on your Schedule-C for your US business as you have done in the past -- i.e.the yearly total income, expenses and the net taxable income.
For your Polish business ( assuming that this is registered in Poland under Polish laws ) , you again report exactly like you report ed your US business on a separate Schedule ( assuming that this is to be treated as a disregarded entity ( note that by default, foreign LLC. sole proprietor business are generally required to be treated as a standalone entity.--- C-Corp usually). Obviously there are ways around this -- consult a tax lawyer familiar with international taxation. For here I will assume that your business in Poland is a Wholely owned subsidiary of the US sole proprietorship and thus can be reported on the same Schedule C as for US business.
The disparity on the reporting of taxes paid ( Foreign Tax credit on your personal return ) should be based on actual income taxes paide or estimated taxed paid ( in which you have to file an amended return when Polish tax authority has finalized the taxes levied ).
Does this make sense ?
If you need more help , please provide more details on your business, especially my assumptions.
Addionally, depending on the actual structure of your foreign entity and its relationship to your US business, you probably would have to file a form 8838 --- Form 8858 (Rev. September 2021) (irs.gov)
