@msj.108 It is looking for the date when you paid /accrued the foreign taxes claimed. TurboTax should have asked for this date -- most people out in 12/31/2020 for the tax year 2020. Note that if the foreign country's tax year is different from that of USA ( for example UK runs from 04/01/2020 through 03/31/2021 ), you have to adjust to make this fit into the US Calendar year ( tax year) -- you have to do the same for the earnings also ( for purposes of foreign earnings and exclusion.
Also form 1116 needs to have the source country entered --- its either RIC / Various for investment income through US brokerage or the Two letter code for the country where the income came from ( source country ) --- this is because you cannot get credit for countries where US prohibits / sanctions interaction.
Does this make sense and solve your issue ?
