I finally found a way to work around the problem of Turbotax refusing to process my payment from a US credit card, and was pleased to see the surprising welcome affirmation after it was received, "We are pleased that you can now send your form to IRS from your foreign address!" A few days later one of the forms blocked it due to my foreign address! Turbotax has strayed far away from the reliable tool I used for many years living and working abroad without any problem. I hope they will review and correct this problem before the next tax year rolls around.
