Line 47600 - Problem in direct input

I have problem on line 47600 (T1 General)

 

My product is TurboTax Home & Business 2024 desktop version.

The software is up to date.

 

I tried to direct input my paid tax amount by instalments, I cannot input my amount.

It didn't display any amount at all, even I press my number keys.

 

Please resolve this problem ASAP.

 

Thanks.
