That is not unusual.  There are many reasons that could result in such a situation; and since this is a public forum you do not want to post your personal information.

Each W-2, 1099, etc is initially processed as if it were the only income you had; thus until you enter ALL W-2s, 1099s, etc your input data is incomplete and hence incorrect.

Make sure you entered the information CORRECTLY and did not mis-type any numbers

The 'monitor' is only a guide (marketing hype).  It is generally meaningless until you have entered ALL of your information since the calculations are inter-related.
