Conversion from string "I" to type 'Boolean' is not valid - vb.net

Question

I am getting this error when I insert several TextBox commands.
Conversion from string "I" to type 'Boolean' is not valid
The code for which I am getting this error is:
If TextBox1.Text = "I" Then TextBox20.Text = "I" And TextBox32.Text = "I" And TextBox44.Text = "I"
If TextBox2.Text = "I" Then TextBox19.Text = "I" And TextBox31.Text = "I" & TextBox43.Text = "I"
If TextBox3.Text = "I" Then TextBox17.Text = "I" And TextBox29.Text = "I" & TextBox42.Text = "I"
If TextBox4.Text = "I" Then TextBox18.Text = "I" And TextBox28.Text = "I" & TextBox41.Text = "I"
If TextBox8.Text = "I" Then TextBox16.Text = "I" And TextBox27.Text = "I" & TextBox40.Text = "I"
If TextBox7.Text = "I" Then TextBox15.Text = "I" And TextBox26.Text = "I" & TextBox39.Text = "I"
If TextBox6.Text = "I" Then TextBox14.Text = "I" And TextBox25.Text = "I" & TextBox38.Text = "I"
If TextBox5.Text = "I" Then TextBox13.Text = "I" And TextBox24.Text = "I" & TextBox37.Text = "I"
If TextBox30.Text = "I" Then TextBox11.Text = "I" And TextBox23.Text = "I"
If TextBox33.Text = "I" Then TextBox10.Text = "I" And TextBox22.Text = "I" & TextBox35.Text = "I"
If TextBox48.Text = "I" Then TextBox47.Text = "I" And TextBox21.Text = "I" & TextBox34.Text = "I"
If TextBox52.Text = "I" Then TextBox51.Text = "I" And TextBox46.Text = "I" & TextBox45.Text = "I"
If TextBox9.Text = "I" Then TextBox12.Text = "I" And TextBox50.Text = "I" & TextBox49.Text = "I"
Any suggestions? They all begin with If TextBox not just TextBox

Answer 1

I fix just one line as an example for the other lines.
If TextBox1.Text = "I" Then
TextBox20.Text = "I"
TextBox32.Text = "I"
TextBox44.Text = "I"
End If
The AND operator is used to execute a logical operation between two expression that result in a boolean TRUE/FALSE result not to repeat the execution of a command.
