No, this will in no way, form or fashion affect you claiming any and all credits and deductions you are entitled too. But by "divorced last year" if you got divorced in 2017, and you are the "custodial parent" as defined by the IRS (not by any court order you may have) then you very well may be able to file Head of Household instead of single. That increases your standard deduction from $12K to $18K for the 2018 tax year.
