ROTH IRA early withdraw

By mistake, I opened a ROTH IRA account and made 1000 dollar contribution in 2020 and then realized the mistake and close the account.  at the time of withdrawal amount is 1045.26.

I received 1099 R from a broker and it mentioned

Column 1 Gross distribution is 1045.62 

Column 2 Taxable amount Blank

Column 2b Checked (Taxable amount  not determined)

 

Column 7: Code is J (indicates that there was an early distribution from a ROTH IRA. )

 

Now Turbotax is adding a tax on the whole amount. please suggest me.

 

I have Tubo Premier desktop version 2020

 

and the taxable amount is blank.
