Doing my Taxes

It is the middle of February, and I recently I downloaded and paid for HR Block "Tax Cut" which I have been using for the past 12 years to do my taxes in the USA (needs to be submitted by Mid-April). I also found a Free Federal Income Tax online program (FreeTaxUSA), which is accepted by the IRS so I am doing both to see if next year I can do to the free online filing. This year putting information in, is more completed (for me) because I sold investments. (Next year I won't have to deal with that again, I sold all my investments on Dec 31, 2019).
I also have to file taxes in Holland (which I have never done before) the beginning of March.....
