I am a US citizen in UK contributing to UK pension. UKUS treaty allows this as US deduction. Where do I enter it in TT or should I lower my foreign earned income amount?
Also, is the maximum allowed deduction for these foreign contributions a) the US limit for US 401k contributions (19,500 USD in 2020 for single filers) or b) the the UK limit used by their tax department (around 40,000GBP)?
