I am experiencing this same loop. Only my income is listed in the Income section, as my wife and I are Married - Filing Separately this year. After selecting Yes to the question of paying for child care in 2021, as well as the Principal Place of Residence being in the US more than half the year, as well as selecting the boxes of the person whose care was paid for living with me for more than half of 2021 and the paid more than half of expenses of maintaining my home, the Continue button reverts me back to the Tax Breaks page without the ability to input the amount paid for Child Care.
