Advice on selecting between Simplified and Standard is not something I can or should advise you on. Most people use Simplified but you may have tax situations that require different treatment.
Note that TT error responses are standardized responses and may or may not reflect the actual underlying issue. As I have mentioned, I got the error notice about AMT as well but when I cleared the 1099-DIV inputs (DO NOT rely on TT to tell you everything is fine because TT does not recognize the error; the IRS will recognize it and TT assigns an error message that is somewhere in the error's solar system) and the Form 1116, then all was well without any AMT changes.
